Seriously, do you know? He's been missing since June. We mentioned last week that he's probably in rehab (also that he's a callow scion who owes everything to the circumstances of his birth, something a lot of you disagreed with!), but that his staff and family are still resolutely refusing to tell his constituents what's going on. His father vigorously denied a report that he'd attempted suicide, insisting that he's just "regaining his strength." An anonymous friend told a Chicago radio station that "he doesn't get a lot of sleep and he has sleep disorders." What do you think? Drugs? Suicide? Chronic illness he wants to keep secret?
